Hi guys, its been a while since i posted anything regarding my 18 kpv. Ill share my story to see if anyone else has been through this.
The way i have been using it is:
- off grid mode with grid backup (when battery reaches 20%, or any % i input, it switches to grid) you can actually hear the contactor switch with a loud sound when it does.
- next day when the sun is out and charges the batteries to 25% it switches back to solar/batteries.
That had been working great for months, but a couple of days back i saw had not updated to the newest firmware, so i did that, it rebooted when it was done, and from that point on it has not worked properly again.
Now its ALWAYS using the grid to power the house, it doesn't matter if the batteries are at 100%, doesnt matter if i am producing 11,000w of solar, it doesnt matter if its off grid or on grid, makes no difference and it doesnt make the sound lf the contactor of you switch on/off values on the off grid menu; so the ONLY was i can use solar and batteries right now is turning off the main breaker from grid supply and manually turning before i go to sleep so the grid takes over until the morning
I regret doing the firmware update so much! I shouldnt have
Any help? Suggestions?
